Hollow-profile composite technology

The described process for producing composite components with hollow profiles and plastic elements addresses manufacturing complexity and strength issues by using an injection mold with a perforated hollow profile to create a form-fitting bond, ensuring mechanical stiffness and preventing collapse, thus enabling the production of composite components with bent profiles.

AI Technical Summary

Technical Problem

Existing methods for producing composite components with hollow profiles and plastic elements face challenges such as manufacturing complexity, weight increase due to additional bonding means, reduced strength and stiffness, and inability to process hollow profiles with bends, especially 90° bends, as well as uncontrollable plastic penetration or collapse of the hollow profile wall.

Method used

A process involving an injection mold with a hollow profile having a bend and a perforation, where plastic is injected into the hollow profile and a secondary cavity, allowing for a form-fitting bond between the hollow profile and a functional element, preventing collapse and enabling the use of bent profiles without additional support elements.

Benefits of technology

This process reduces manufacturing complexity, maintains strength and stiffness, and allows for the production of composite components with functional elements bonded radially and axially in a mechanically stiff manner, while preventing hollow profile collapse and enabling the use of bent profiles.
